Mapping Teacher Beliefs and Practices About Multilingualism: The Development of the MultiBAP Questionnaire

This chapter provides a detailed description of the methodology behind the development of a new questionnaire instrument called MultiBAP (Multilingualism: Teacher Beliefs And Practices). As part of the school-based research project MultiLingual Spaces (see  Källkvist et al., 2017) – in which multilinguals are defined as learners of English who use Swedish and one or several additional languages (e.g. Arabic, Finnish or Somali) in their everyday life – MultiBAP was designed to map L2 English teachers’ beliefs about multilingualism in individuals, in classrooms and schools and in Swedish society at large, and practices in their classrooms and schools.
